Our origins in the hewing of stone go back 1970 with the opening of Mármoles Eduardo Beltrá Mira that when his retirement in 1986 became Mármoles Beltrá C.B. where after investigation time manages to solve the problem of sharpened without distemper the steel tools, inventing the Whetstone made of natural stone WITH STEEL SOUL, being this tool a world innovation patented, developed and founded by Eduardo Beltrá Méndez, in October, 2007. Him and his son, Eduardo Beltrá Sanz, join together and there is born MARMOLES BELTRÁ Y SANZ S.L. Where they get the experience of almost 40 years in the craft of the stone with the implantation of new technologies, the propulsion and the illusion that the youth brings.
“A pedra das meigas.”
We have several types of natural sharpening stone. There are two different ones that stand out:
The silicon-ferric one, with a big emptying power and an ideal grain for this assignment, being able to leave the knife-edge with the finished that she leaves if the tool that we sharpen doesn’t need a thinner finished.
Ideal finished for agricultural, industrial uses, even in kitchen.
The second natural stone, and real magic in the sharp is the knife-edge placer.
His natural characteristics together with the processes of treated make her the only whetstone on the market, gives to our steel tools the best quality of delicacy and completion in the sharpen that turns our old and rejected tool into the perfect coworker.
We increase our variety of whetstones, due to we can always apply more of our transformation techniques in order to reach the properties that our customers needs.
Nowadays with the new technologies, we can give forms even to combine two stones in one, thanks to the powerful adhesives that exist. Making use of these we obtain two well different scales of products:
The first one consists in combined formats of one stone or the combinations of the two stones that make them indicated for different uses and needs.
The second one consists in formats that the natural stone would not support if we don’t introduce the stainless steel soul in the interior. Real advance and patent of our property, that it allows us to go on from simple natural stones of sharpened to a real tool of daily use.
